It's never easy to crack into a market with a innovative new product but makers of the "world's first smart fingerprint padlock" have made one critical error: they forgot about the existence of screwdrivers.

Tapplock raised $320,000 in 2016 for their product that would allow you to use just your finger to open the "unbreakable" lock. Amazing. Things took a turn for the worse when the ship date of September came and went and backers complained that the company has stopped posting any updates and wasn't responding to emails or social media posts.
